Albert ARIBAUD (3ADEV) 38e70dfb74 Preprocessor directives for addons
This patch augments the XML dumps with a 'directivelist'
subnode which lists all raw preprocessor directives met
while reading the source code in each configuration.

Also, the addons/cppcheckdata.py file has been extended
to give easy access to the list of directives and to
provide Python support for the --template (or short -t)
option.

Finally, an new addon, addons/y2038/y2038.py, is created
to detect when a glibc symbol might be Y2038-sensitive,
based on whether and how _TIME_BITS and _USE_TIME_BITS64
are defined when meeting the symbol.

Albert ARIBAUD (3ADEV) df91caafa1 Fix trim() in lib/Preprocessor.cpp
Currently, if its argument is all spaces and tabs,
trim() returns it without actually trimming it.
Fix this by returning an empty string in this case.
Also, drop a useless test: if we did not return ""
then beg is not equal to std::string::npos, and in
that case, neither is end.

Albert ARIBAUD (3ADEV) e7fdb1c825 Fix multiple config dumps
With multiple configurations, option --dump only dumps
the last configuration.

Fix it to dump every configuration.

Also update all Python addons so that they can handle
multiple-configuration dumps.

Additionally run autopep8 on addons/*.py.

The results of 'make test' before and after applying
this commit are identical.
